Chapter 2 Technical Architecture and Consensus Mechanism

2.1 Core Architecture and Design Philosophy

With "modularity, expandability, and native AI embedding" as its design philosophy, the core architecture of Super AI Chain is divided into four layers, and each layer collaborates to ensure the efficiency and security of the network:

• Application Layer: Decentralized applications (dApps) covering scenarios such as finance, insurance, and transactions, supporting developers to quickly build based on EVM.

• Function Layer: Including the smart contract layer (compatible with EVM, supporting Solidity development) and the AI core layer (Super AI, natively embedded in the public chain protocol). The former ensures the compatibility of the developer ecosystem, while the latter provides intelligent risk control and earnings optimization.

• Consensus Layer: Adopts the DPoS + BFT hybrid consensus. DPoS is responsible for node election and block production, and BFT ensures the finality of transactions and network consistency.

• Node Layer: Hierarchical design of main nodes, auxiliary nodes, and light nodes, balancing network efficiency and decentralized coverage.

Architecture Table

Hierarchical Structure	Core Module	Key Functions & Value
Application Layer (Application)	dApps/Smart Contract Layer	Supports the rapid deployment of decentralized applications (dApps) in scenarios such as finance, trading, and insurance. Fully compatible with EVM, supporting rapid migration of external projects (PCS strategy).
Function Layer (Function)	Smart Contract Engine	Compatible with EVM, supporting mainstream languages such as Solidity, ensuring the versatility of the developer ecosystem.
	Super AI Core Layer (AI-Native)	Natively embedded in the protocol layer, driving core intelligent decisions: dynamic adjustment of the SIP risk control threshold, optimization of DeFi earnings strategies, and regulation of ecological dividend rates.
Consensus Layer (Consensus)	DPoS + BFT Hybrid Consensus	DPoS (21 main nodes) ensures high TPS and efficient block production; BFT ensures the immediate finality of transactions, meeting the security requirements of financial-grade scenarios.
Node Layer (Node)	Hierarchical Node System	Main Nodes (21): Core block production and security; Auxiliary Nodes (101): Redundant transaction verification and network decentralization; Light Nodes: Low-threshold participation, expanding network coverage.

2.2 Consensus Mechanism: DPoS + BFT Hybrid Model

Super AI Chain combines the efficiency of DPoS and the security of BFT to achieve the dual advantages of "fast block production + immediate confirmation":

• Division of Labor and Advantages of DPoS: SUP token holders vote to select 21 main nodes and 101 auxiliary nodes. Main nodes are responsible for block generation and transaction packaging, with an average block time of 2-3 seconds and a theoretical TPS of thousands of transactions; auxiliary nodes assist in verifying transactions and reducing the load of main nodes.

• Division of Labor and Advantages of BFT: Adopt the Byzantine Fault Tolerance algorithm to immediately confirm the blocks generated by main nodes. The irreversible time of transactions is 1-2 seconds, effectively preventing double-spending and malicious attacks, and meeting the security needs of financial scenarios.

• Hybrid Collaboration Logic: DPoS solves the efficiency problem of "who will produce blocks", and BFT solves the security problem of "whether the blocks are credible after production". The combination of the two makes Super AI Chain suitable for both high-frequency transactions and large-value asset settlement.

Core Node Information Table

Node Type	Quantity	Core Responsibilities	Incentive Rules (Core Summary)
Main Node (Validator)	21	Block generation, transaction packaging, network security maintenance	Basic Reward: Core share of mining output (upper limit ≤ 100 times of own staking); Additional Reward: 20% of ecological derivative interest
Auxiliary Node (Guardian)	101	Redundant transaction verification, cross-node forwarding, consensus assistance	Basic Reward: Share of mining output (upper limit ≤ 50 times of own staking); Additional Reward: 20% of ecological derivative interest
Light Node	Unlimited total (1,000 in the first batch)	Contribute bandwidth, lightweight block verification, low-threshold user participation	Basic Reward: 3-12 months of staking earnings; Additional Reward: 20% of ecological derivative interest (upper limit ≤ 20 times of own staking)

Light Node Auction Mechanism (Competitive Auction - Highest Bidder Wins)

• Auction Rules: Organize a competitive auction once a month with a starting price of 10 SUP tokens; after the auction period ends, sort by bid price from high to low, and select the top 1,000 bidders (quota for the first batch) as winners. For users with the same bid price, the one who bids first has priority.

• Winning Rights: Winning users need to stake SUP for 3-12 months. During the staking period, they enjoy the basic mining earnings corresponding to the period, and at the same time obtain 20% of ecological derivative interest (upper limit ≤ 20 times of their own staking).

• Protection for Non-Winners: The auction funds of non-winning users will automatically enjoy an annualized return of 2.5% for 7 days. After the earnings are credited, the principal will be returned via the original route to ensure risk-free participation.
